Abstract [sv]

Allting började med att jag fick i uppdrag av Euromaint Industry i Skövde att konstruera en alfanumerisk display i syfte att ersätta en utgången display som inte längre nytillverkas. Jag fick i uppdrag att välja ut en modern, lämplig grafisk display och bygga ett interface mellan den nya displayen och den industriella maskin som displayen skall sitta på. Efter att ha letat hos någraelektronikleverantörer kom jag fram till att en TFT-skärm från det japanska företaget Kyocera var den som passade bäst. Skärmen hade ett VGA-liknandeinterface och min uppgift blev att sätta mig in i hur VGA fungerar. Efter att ha konstaterat att det krävdes en snabbare krets än en microcontroller för att använda VGA, var det endast en programmerbar logikkrets, en FPGA, som gällde. Denna FPGA sköter nu ensam om såväl VGA-interfacet som inläsningen av informationen från den industriella NC-maskinen.

Abstract [en]

Everything started when I got a task from Euromaint Industry in Skövde, Sweden, to develop an alphanumerical display that could replace an old one, which was sold out. I got a task to choose a modern, suitable, graphical display and develop an interface between the new display and the industrial machine, which the old one was connected to. I have searched for a display at some suppliers of electronic components and I have found a TFT-display from the Japanese company Kyocera. The display had an interface similar to VGA so I had to study VGA to see how it works. Then I realized that I needed a faster circuit than a microcontroller. Then I chose a programmable logic circuit, an FPGA, to control the VGA-sweep. Today the FPGA-circuit controls the whole system.
